プラスチック歯車とアルミニウム合金歯車対の運転特性に関する研究

Recently due to increased usage, there are many instances where plastic gears are used in combination with aluminum alloy gears. In these cases, since aluminum alloy gears are considerably softer than steel gears, the tooth surfaces become extremely worn and rough, and it is feared that the phenomenon of multiplied effect promoting the wear of plastic gears by such rough tooth surfaces may occur. Thus, in this study, an operating test was carried out by combining an MC nylon gear and an aluminum alloy gear, and the actual conditions of the wear of teeth, the roughness of tooth surfaces, the temperature of teeth, the change of tooth profile and so on were investigated.
